and presumably molten magma.
Not so sure about going through rock though.
Good news for mole-cruiser fanciers today, as boffins reveal important new developments in the technology of burrowing subterranean machines. Poster art for the 70s film of At the Earth's Core by Edgar Rice Burroughs Traditional mole cruiser in action. The new underground locomotion tech comes from Professor Daniel Goldman …
As fun as the concept and descriptions are...
How about filling the mole with spent nuclear waste and driving a cheap one a safe distance from a geological fault line. That was as the tectonic plate passes over the area the nuclear waste gets buried under an entire continent and recycled in the magma flows? I would imagine that the mole itself would be melted by the magma and perhaps the whole thing would get crushed to the size of a football over a few million years by which time the radioactivity has decayed into something benign?
Japan could make a new business of burying nuclear waste under China.

And in other news, the recent volcanic eruption near Shenzhen has irradiated an area the size of Australia after it released more than 50,000 tons of high-level nuclear waste into the atmosphere, which had been buried there by Japanese burrowing machines for the past 20 years. UN secretary-general Wadda Fukizat says more than five million square miles of central Asia will be uninhabitable for at least the next 275 millennia, and we can expect to see a sharp increase in the number of two-headed goats, kittens and babies born around the world over the coming decades.
